I wonder if the porous bronze part could be solidified by wicking another (molten) metal into it, the way Bathsheba Grossman’s sculptures are first printed in stainless steel powder, sintered and burned out as in this process, and then infused with molten bronze.
Obvious metals to try to solidify bronze in this way would be tin, zinc, lead, and (if you can somehow control oxidation) aluminum. Cadmium or mercury might also work but are attended with difficulties that probably make them impractical.
